Description

Leveling vibration and noise prevention device for easy leveling

The present invention relates to an interlayer vibration and noise preventing device installed on slabs of various buildings such as apartment houses to prevent vibrations or noises applied between floors, and to shorten the assembly time of the panel and to complete the assembly of the panel. It is possible to easily adjust the height of the panel by using, and the damping member rotates freely according to the surface state of the inclined or curved slab so that the panel closely adheres to the slab. It relates to a noise prevention device.

Recently, inter-floor vibration and noise in apartments such as apartments and multi-family houses have emerged as an important issue.

As shown in Fig. 1, the general building structure of a multi-unit house is a structure in which horizontal slabs 11 are poured between vertical walls 10. The upper surface of the slab 11 is provided with a heat insulating material 12, the foam concrete 13 is poured on the upper portion of the heat insulating material (12).

The foamed concrete 13 performs a self leveling function as a slurry in which chemicals are added to concrete.

A bottom heating layer 15 is formed on the foam concrete 13, and a heating pipe 14 for supplying hot water is embedded in the floor heating layer 15.

By the way, in the multi-family house as described above, because the wall 10 and the slab 11 and the floor heating layer 15 are connected to each other in the form of a box, the vibration and noise between the floors 10 and the slab 11 are prevented. Is passed on.

In order to prevent vibration or noise generated between the floors of the building, there must be a part capable of absorbing the same. In the conventional structure as shown in FIG. Therefore, the vibration and noise generated in any one layer can be transmitted to the adjacent several layers through the wall 10 and the slab 11.

In recent years, houses are not merely residential, but are recognized as spaces where privacy can be protected. The above-mentioned multi-unit housing is difficult to prevent vibration and noise in its structure.

As a solution to this problem, there is a method of increasing the thickness of the slab (11). However, even in such a manner, since the wall 10 and the slab 11 are integrally connected, it is difficult to expect a satisfactory interlayer vibration and noise prevention effect.

In addition, when the thickness of the slab 11 is increased, the thickness of the wall 10 supporting the slab 11 must also be increased. This is undesirable because it increases the weight of the whole building and consequently leads to an increase in construction cost.

As another method of preventing vibration and noise, there is a method of inserting various dustproof pads between the slab 11 and the floor heating layer 15 or forming a waste tire dustproof layer.

However, as described above, the method of forming the anti-vibration pad or the anti-vibration layer also becomes an integrated structure with the slab and thus cannot solve the above-mentioned problems.
